CUTTER-STAY FOR FLOWS.

Specification of Letters lPatent. i

Patented Dec. 22, 1908.

Application led June 30, 1908. Serial No. 441,254.

To all whom 'it may concern:

Be it known that I, JOHN O. L. ADAMS, a citizen of the United States, residing at Saylor, in the county of Haskell and State of Oklahoma; have invented certain new and useful Improvements in Cutter-Stays for Plows, of which the following is a'speciiication, reference being vhad to the accompany -ing drawings. l

My invention is animproved' brace or stay for connecting acutter bar or equivalent device to the beam of ment.

The principal object of the invention is to'.

provide a simple, inexpensive, and practical device of this characterwhich will effectively brace the cutter so that when applied to an ordinary plow the latter may be eectively used to plow new ground.l 1

With the above and Vother objects in'view, the invention consists' of the novel features of construction and thecombination and arran ement ofl parts hereinafter fully .de-

scri ed and claimed, and illustrated vinthe accompanying drawings,A -in whichw-i r Figure 1 is a side elevation of a plow showing my invention applied thereto for bracing an vupright cutter bar; Fig. 2 is across sectional view taken on the plane indicatedby the line 2-2 in Fig.v 1; and Fig. a detail section taken on the plane .in'dicatedby theV line 3 3 in said gure.

In the drawings 1 denotesthe beam of a vplow or analogous implement, 2' an upright cutter bar and 4my improved brace or stay which is arranged between the latter and the front portion of the beam. The cutter v2 has a flat upper end or shankfi which may be fastened to the beam 1 in any suitable manner,

butwhich is here shown as clamped against one side of said beam by a clam 5i consist-- Aing of flat plates or bars 'united y clamping' bolts. The lower end of the cutter. is enlarged and has its lfront edge beveled or sharpened to provide a 'cutting-edge which vwhen appliedA to theplow is disposed infront of the plow share on the standard at the rear of the beaml 1.

My improved brace or stay 3 comprises a rod formed at its opposite ends with eyes 5, 6 which are disposed in planesat right angles to each other. The eye 6'at the lower or rear end of the brace rod is arranged between a plow or similar impletwo clamping plates 7 engaged with the opposite sides of the cutter 2 and formed adjacent to their ends with alining apertures to receive clamping bolts 8, one of said bolts passing through the eye 6, as 4clearly shown in Fig. 3 to simultaneously secure the clamp to the cutter andthe brace'rod to the clamp.l The upper or'forward end of the brace rod is j `connected to the beam by a clamp which consists-of four eye .bolts 8 theu threaded shank of each'of which is passed through the eye of one of the others and is adapted to re .ceiveanut 9. The eye bolts 8 are so ar.- -ranged as to receive the beam 1 between them in order that when.v the nuts 9 are tightened they' will effectively clamp the beam'. One of the eye bolts 8 passes through the eye '5 on thebrace rod so that the clamp serves to unitethe latter to the beam.

-Itwill be noted that the invention is eX- ceedingly simple 'in construction' so .that it maybe produced vat a small cost and will be strong and effective'.

'While :the invention is especially designed -for use in bracing the lower portion of an upright cutter bar upon a plow in order that an :ordinary plow may be eifectively used for plowinga new ground, it will be understoodthat it may be used for analogous purposes on plows'and other implements. Having thus described my invention what Y Iv claim 1s:

1. A brace for connecting a cutter bar or the like tothe beam-of a plow or similar implement comprising rod having an eye at one end, means at its other end for connecting it to a cutter bar, and a beam engaging clamp consisting of eye bolts, each having its threaded end passed through the eye of one of the others, one of f ie bolts being passed through said eye lat the end of the rod.-

2. A- clamp consisting of a plurality of eye bolts, each having its threaded end passed through the eye of one ofthe others and nuts upon the threaded ends of said bolts.

Inl testimony whereof I 'hereunto 'afhX my signature in thepresence of two witnesses.

JOHN C. L. ADAMS.
